Abstract
The present invention is a method and apparatus for enhancing a perceived video quality (e.g. higher resolution) on a display in a region surrounding an intersection point of a user's gaze onto a screen of the display.
Claims3
An apparatus comprising:
- an eye tracking system for determining an eye-gaze direction line of a user looking at a display screen of a display device;
- an eye-gaze tracking module for extracting the eye-gaze direction from the eye tracking system and for determining the intersection point where the eye-gaze direction line intersects with the screen;
- wherein the eye-gaze tracking module sends the intersection point data to a scalable video decoder;
- wherein the scalable video decoder receives an encoded video stream and provides a first set of higher video resolution data for a first region surrounding the intersection point on the display screen and a second set of lower video resolution data to a second region of the video screen that is different than the first region;
- and
- wherein the second region on the video screen is dimmer than the first region on the video screen.

- an eye-gaze tracking module for extracting the eye-gaze direction from the eye tracking system and for determining the intersection point where the eye-gaze direction line intersects with the screen;
- wherein the eye-gaze tracking module sends the intersection point data to a scalable video encoder;
- wherein the scalable video encoder receives a source video stream and provides an encoded first set of higher video resolution data for a first region surrounding the intersection point on the screen and an encoded second set of lower video resolution data is provided for a second region of the screen that is different than the first region;
- and
- wherein the second region on the video screen is dimmer than the first region on the video screen.
